technical field [0001] The invention relates to the technical field of motor speed regulation experiments, in particular to a method and system for motor speed regulation experiments based on dynamic loading of signal flow diagrams. Background technique [0002] The traditional motor speed regulation experiment is carried out in the way of dynamic loading, and its structure diagram is as follows: figure 1 As shown, the speed regulation motor adopts the speed regulation control algorithm embedded in the core chip of the speed regulation motor controller to implement speed regulation control to achieve the purpose of real-time speed regulation; the loading motor uses the loading control algorithm embedded in the core chip of the load motor controller to implement Loading control to make the speed regulating motor obtain a given motor load in real time; the torque speed sensor is used to measure the torque and speed of the speed regulating motor in real time, and its supporting...

Problems solved by technology

[0003] In specific operations, there are mainly two types of schemes. One is to customize the automated experimental method according to the needs. This method is a customized method that requires long-term planning to avoid errors in a certain link, which will cause the preparation time cost in the early stage. Higher will also increase the difficulty of the experiment; the other is to decompose the existing requirements and use a variety of simple methods to conduct experiments. This method is a decomposition method, which will greatly increase the uncertainty of the experiment due to the accumulation of various links sex

In addition, in the above two schemes, the amount of manual input is difficult to predict. Although increasing the amount of manual input is conducive to ensuring the safety of the experiment and reducing the risk of the experiment, the artificial response ability is limited after all, and there is a shortcoming of insufficient timeliness. At the same time, if the artificial Excessive investment will greatly increase the possibility of repeated experiments, so as to increase the cost of experiments

[0004] In summary, the traditional motor speed control experiment method is difficult to balance the relationship between experiment risk, experiment cost and experiment efficiency, and there are technical problems of high experiment risk, high experiment cost and low experiment efficiency.
